Flygt Submersible Pumps 

FOR CONSTRUCTION aNd MINING

Over 60 years of dependable pumping 

Construction workers and miners have come to trust the 

compact, heavy-duty design of Flygt submersible pumps 

since they were developed more than sixty years ago. 

Flygt was the first to offer a practical, heavy-duty electric 

submersible pump that could withstand the severe 

demands of construction site and mine dewatering 

and yet still be portable. Over time these early 

submersibles became the prototype for a complete 

range of other hard-working Flygt submersible pumps, 

all built in the same tradition of dependability. 

We know from years of experience what it takes 

to design and manufacture the finest heavy-duty 

submersible equipment. The high tolerance machining 

is a standard manufacturing process for all parts that 

make up our products. We know from experience 

that it takes many precise steps, along with quality 

O-rings, to achieve the exceptional “fit” needed to 

keep a submersible motor dry. This includes critical 

sealing areas, such as where the power cable enters 

the pump. All parts are machined so the right amount 

of compression force is applied between the sealing 

grommet, cable and pump body, each and every time 

the cable entry bolts are tightened. The result is 

a dependable compression cable seal, which can 

easily be serviced in the field, and does not require 

epoxy sealers. 

Precision machining with the outer stator core 

diameter and inner motor housing surface allows us to 

precisely shrink-fit the motor stator core into the housing. 

This feature provides a uniform metal-to-metal contact 

between the heat producing motor and its housing, 

resulting in exceptional cooling without the need for 

messy, expensive cooling oil.

The original submersible 

pumps had a distinctive 

bell-like shape. 

Continuing its tradition of excellence, Xylem has 

recently introduced its latest generation of Flygt pumps. 

Designated the 2600 series, the new dewatering pump 

line features innovative hydraulics, fewer components, 

new materials and a practical, ergonomic design. The 

patented DuraSpin hydraulic system and newly 

designed impeller improves wear resistance and 

sustains performance over time. The wear-resistant 

closed impellers are made from high-chrome cast 

iron. A single screw enables fast and easy adjustment 

for maximum pump performance. During scheduled 

maintenance, a moderately worn hydraulic end can 

be quickly adjusted back to virtually full performance. 

The unique one-piece Plug-In seal incorporates two 

mechanical seals for double protection against liquid 

penetration. 

The results of these features together 

in one pump: 

• Unmatched wear resistance 

• Consistent long-term performance 

• Less downtime resulting in the lowest possible cost 

of ownership 

• Three times more wear-resistant compared to 

traditional dewatering pumps 

Xylem and Flygt continues to offer the most complete 

range of heavy-duty submersible pumps, backed by 

a nationwide network of service centers stocked with 

genuine Flygt pumps and parts. When dependability 

counts, specify the best… specify Flygt pumps. 

The earliest electric submersible dewatering pump, developed by Flygt, 

was called the “Parrot Cage” after its unusual look. In 1948 the first 

practical version, model B-80, went into full production and became the 

prototype for a complete line of other hard working submersibles, all 

built in the same tradition of dependability.

The pumps in the 2600 series cover almost any dewatering application at worksites of all sizes, including construction sites, mines, 

quarries and other harsh environments. The slim design allows the pumps to be installed in pipes used for active dewatering. High 

wear-resistance and ease of service make 2600 series pumps the clear choice for contractors. 

Compact Flygt pumps can be installed virtually anywhere dewatering 

is required. Multiple pumps equipped with high volume impellers 

allow large amounts of water to be pumped quickly. Flygt’s exclusive 

motor design places the heat producing stator in direct contact with 

the motor housing, which provides optimum cooling even under 

non-submerged conditions. 

4 

Flygt submersible pumps are routinely used to remove abrasive, 

dirty water from quarries with steep embankments and severe 

heights. When equipped with high-head impellers, check valves 

and optional tandem coupling kits, submersible pumps offer an 

excellent solution. Quarry installations can also include mounting the 

pump from a floating raft to keep it off the rough or soft bottom 

and accommodate varying water depths.

1. Terminal board 

Additional barrier to water ingress. Screwless spring loaded 

terminal assures reliable connections and simplifies wiring. 

2. External oil and inspection plugs 

The external oil plug facilitates service, with no need to 

disassemble the pump to refill or check the condition of the oil, 

as well as providing easy access to the inspection chamber. 

3. Inspection chamber 

The inspection chamber provides early notification of any 

fluid buildup in case of seal leakage, minimizing the risk 

of expensive repair work. 

4. Plug-In Seal 

The special one-piece Plug-In seal incorporates two 

mechanical seals for double protection against liquid penetration. 

The unit enables faster and simpler replacement, and 

protects seal surfaces during disassembly and mounting. 

5. Spin-Out 

Unique to Flygt products, this patented design protects the 

outer seal and extends service life by expelling abrasive 

particles from the seal. 

6. Impeller 

* K impeller, optional 

The high-chrome closed impeller is our standard design, made 

to handle a high level of abrasives. Additionally, we have the 

high-chrome open *K impeller, designed to minimize the 

clogging associated with pumping large stringy solids. 

7. Single adjustment screw 

A single screw enables fast and easy impeller adjustment 

for optimal performance over a sustained period of time. 

8. Dura-Spin hydraulic system 

Spiral grooves on the suction cover, in combination with back 

vanes on the impeller, provide greatly increased durability by 

preventing abrasive particles from reaching the impeller neck.

S/KS series dewatering pumps 

These are popular Flygt dewatering pumps, known for job site dependability. Most models have strong, lightweight 

aluminum and stainless steel body parts and feature hardened impellers with nitrile rubber adjustable wear parts for 

long life. These tough pumps do not require total submersion, and will operate under snore conditions if necessary. 

Many are available in MSHA-certified, explosion-proof versions for use in mining or landfill dewatering.

Solids-handling dewatering pumps 

VORTeX IMPelleRS 

Pumps equipped with a vortex impeller are suited for pumping water containing moderately abrasive or stringy 

solid materials which tend to clog conventional centrifugal impellers. The “open” impeller is located and turns at the 

top of the pump chamber, causing a powerful vortex that induces a pumping action in the water below it. Since most 

of the pumped water does not actually pass through the impeller, wear and clog-potential are minimized.

ClOSed IMPelleRS 

CS models feature closed wastewater impellers designed for pumping typical wastewater solids as found in many 

sewage applications. Usually, a stationary brass or nitrile rubber wear ring is set into the volute bottom, surrounding 

the lower part of the impeller, to prevent wear and maintain hydraulic efficiency. Larger models may also utilize a 

stainless steel rotating ring, tightly fitted around the lower part of the impeller, to further reduce wear.

N–IMPelleRS 

All NS series pumps are equipped with Flygt’s innovative “self-cleaning” N-impeller. The open impeller works 

with a special relief groove at the bottom of the volute to continually keep it free from solids build-up. This 

proven design not only reduces clogging but also ensures continued long-term efficiencies, which significantly 

reduce electrical operating costs. An excellent choice where troublesome solids are present in the water to 

be pumped.

Heavy-duty slurry pumps 

HS 5100/5500 series pumps will easily handle extremely abrasive slurries containing sand, gravel, grit or ash, without 

damage. Both the impeller and pump casing are made of high chrome alloyed cast iron, for maximum abrasion 

resistance. The HS 5100 series pumps use a one-piece pump casing, while the HS 5500 series have a replaceable liner 

of high chrome alloyed cast iron. Heavy-duty mechanical seals are protected by a unique expeller and pressure isolation 

chamber. The optional agitator, when attached to the shaft, resuspends particles around the pump inlet.

Flygt accessories 

Automatic Level Control Systems 

Flygt offers a family of automatic controls that allow unattended operation of Flygt 

portable pumps. They are available with either two Flygt ENM-10 level sensors or 

with FPC 100 controller. The FPC 100 allows for automatic pump operation without 

using floats or level sensors. 

Manual Control for Medium and Large Portable Pumps 

Manual Control for Small, Portable Flygt Pumps: 

Zinc Anodes 

A complete range of manual controls are available for medium and large Flygt 

portable submersible pumps. Each NEMA 4X enclosure is equipped with the 

correct circuit breaker/overload for pump protection of the model involved. 

These strong, rugged units allow easy manual control and full electrical 

protection for smaller Flygt portable submersibles. Flygt short-circuit and 

overload protection, along with starting components for single phase models, 

housed in a NEMA 4X watertight and corrosion resistant enclosure. 

High grade zinc anode kits are available for most Flygt submersible pumps to 

help protect against the damaging effects of galvanic corrosion. The anodes are 

easily mounted to the pump with the stainless steel hardware provided. Specify 

exact pump model when ordering.

Tandem Coupling Kits 

Flygt FPC100 Pump Controller 

Flygt Pump Flotation Modules 

Low Suction Collar 

Tandem connections are available for most models, allowing the pump to be 

connected in series with another Flygt submersible to help overcome severe 

vertical heights. Easily installed after the strainer is removed, allowing the connecting 

hose from another pump to be attached with clamps. Consult your nearest Flygt 

supplier for pressure limitations and other application requirements. 

The Flygt FPC 100 Automatic Controller is used primarily for dewatering pumps in 

construction and mining applications where ordinary level sensors are not the best 

choice. The FPC 100 offers entirely automatic pump control without the need for 

components built into the pump or separate level sensor arrangements. 

Flygt pump flotation modules (PFM) have been developed to provide a light-weight 

and cost-effective alternative to traditional steel pontoons. The flotation modules 

are prefabricated from strong polyethylene with foam filling. The pump floats close 

to the surface, increasing the pump’s service life and reducing maintenance since 

the pump is no longer working in a high solids environment. 

The Flygt low suction collar removes unwanted water down to very low levels 

when required for emergency services. This works with models 2610, 2620 

and 2640.
